TELEG RAPHIC RELAY.

SPECIFICATION forming part of Letters Patent No. 655,716, dated August 14:, 1900.

Application filed May 20, 1899- Renewcd December 21, 1899. Serial No. 741,189. (No model.)

T 00% whom, it may concern:

Be it known that I, ISIDOR KITSEE, of the city and county of Philadelphia, State of Penn sylvania, have invented certain new and useful Improvements in Telegraphic Relays, of

which the following is a specification.

My invention relates to an improvement in telegraphic relays, and has more especial reference to relays for wireless or space teleg- IO raphy.

The object of my invention is to produce a relay for the incoming electric waves.

The current impulses used in wireless or space telegraphy are of such high intensity that their static influence is felt on a conducting material supported by a dielectric material if this conductor is placed in proximity to a conductor carrying these electric waves of high intensity. It is well known that such a conductor in proximity to a charged conductor will first be polarized, then attracted, and then repelled, if capable of such movement, and my invention is based upon this principle.

Referring to the drawings, Figure 1 is a side elevation, partially in section. Fig. 2 is diagram showing the electrical connection.

A is the non-conducting base; B, the noncondncting support for the diaphragm O.

This diaphragm may be entirely made of a conducting material, such as a thin sheet of metal, or it maybe made of a non-conducting material, such, for instance, as gold-beater skin, provided as to its center on both sides 3 5 with a conducting material.

D is a metallic ring holding the diaphragm in place.

0' is the binding-post in electrical connection with the diaphragm, and if this dia-- 40 phragm is of non-conducting material it is obvious that the conducting center piece has to be either with the aid of a very thin and flexible metallic thread or through the aid of gold leaves pasted on the diaphragm or by other 5 well-known means to be brought in electrical contact with this binding-post.

E and F are metallic supports for the metallic contact-screws c and f, respectively. e and f are their respective binding posts.

5o Gis a glass globe covering the instrument.

The binding-post c is connected through wire t with the receiving instrument K, through wire 5 with the battery J, and through wire 1 with the binding-post c, which binding-post is in electrical connection through wire 6 with the aerial conductor H. The binding-postf is through wire 8 connected to the ground L. I prefer that the conducting part of the diaphragm 0 should normally be in contact with screw 6. The circuit containing the battery and electromagnetic device is therefore normally closed.

' The working of the device is as follows: When electric impulses are received with the aid of the conductor H, the same will travel through wire 6, binding-post e, supportE,and adjustable screw 6 to the conducting part of the diaphragm C, charging the same with the same potential as the'screw c. It will therefore be repelled and attracted toward the screw f, tending to charge the same, and will then be again repelled and will come to rest at the point of screw 6. This action will open and close the circuit containing the battery J and the receiving device K, thereby actu- 7 5 ating the same. This device can also be used in a manner so that normally none of the adj ustable screws should be in contact with the conducting part of the diaphragm C; but I have found the working of the device far 8o more satisfactory and more reliable if the conducting part of O normally rests against. the screw 6.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In telegraphy a static relay consisting of a vibrating diaphragm, partially or wholly conducting in electrical contact with a circuit containing a generator of electricity and go a receiving device, in juxtaposition to a conductor electricallyconnected to the battery circuit and the aerial conductor, in combination with a conductor connected to the ground.

2. In telegraphy a relay consisting of two conductors in proximity to each other, one of said conductors being connected to the aerial conductor and one terminal of the local circuit containing a battery and a receiving device, the other conductor being connected to 103 the ground, in combination with a vibrating diaphragm, partially or wholly conducting,

placed between said conductors, the diaphragm being connected to the second terminal of the circuit containing the battery and receiving device. 7

3. A static relay consisting of a vibrating diaphragm Wholly or partially conducting, in electrical contact with an adjustable conductor connected to one terminal of the receiving-circuit, a second adjustable conductor to placed in proximity but out of electrical connection With said vibrating diaphragm, said second adjustable conductor being connected to the other terminal 01; the receiving-circuit.

In testimony whereof I sign my name,in the presence of two subscribing Witnesses, this 15 19th day of May, A. D. 1809.
